Rose plant named ‘Chewperadventure’

ABSTRACT

A new and distinct cultivar of Rose plant named ‘Chewperadventure’, characterized by its outwardly spreading and low mounding plant habit; glossy dark green-colored leaflets; freely branching growth habit; dense and bushy plant form; freely and continuous flowering habit; large salmon red-colored flowers; resistance to Black Spot; and good garden performance.

Botanical designation: Rosa hybrida.

Cultivar denomination: ‘CHEWPERADVENTURE’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Rose plant, botanically known as Rosa hybrida, commercially used as an ornamental shrub and hereinafter referred to by the name ‘Chewperadventure’.

The new Rose plant is a product of a planned breeding program conducted by the Inventor in Brockton, Newport, Shophire, United Kingdom. The objective of the breeding program was to develop new ground cover Rose plants with improved disease resistance and attractive flower coloration.

The new Rose plant originated from a cross-pollination made by the Inventor in 1997 of Rosa hybrida ‘Chewpobey’, not patented, as the female, or seed, parent with an unnamed selection of Rosa hybrida, not patented, as the male, or pollen, parent. The new Rose plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Brockton, Newport, Shophire, United Kingdom.

Asexual reproduction of the new Rose plant by softwood cuttings at Brockton, Newport, Shophire, United Kingdom since 2000, has shown that the unique features of this new Rose plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Chewperadventure’. These characteristics in combination distinguish ‘Chewperadventure’ as a new and distinct Rose plant:

-   -   1. Outwardly spreading and low mounding plant habit.     -   2. Glossy dark green-colored leaflets.     -   3. Freely branching growth habit, dense and bushy plant form.     -   4. Freely and continuous flowering habit.     -   5. Large salmon red-colored flowers.     -   6. Resistant to Black Spot.     -   7. Good garden performance.

Plants of the new Rose differ from plants of the female parent, ‘Chewpobey’, in the following characteristics:

-   -   1. Plants of the new Rose have larger leaves and leaflets than         plants of ‘Chewpobey’.     -   2. Plants of the new Rose have larger flowers than plants of         ‘Chewpobey’.     -   3. Plants of the new Rose and ‘Chewpobey’ differ in flower color         as plants of ‘Chewpobey’ have orange red-colored flowers.

Plants of the new Rose differ from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Rose are more low mounding than and not as         upright as plants of the male parent selection.     -   2. Plants of the new Rose and the male parent selection differ         in flower color as plants of the male parent selection have         pink-colored flowers.

Plants of the new Rose can be compared to plants of Rosa hybrida ‘Horcoherent’, disclosed in U.S. Plant Pat. No. 15,982. In side-by-side comparisons, plants of the new Rose differ primarily from plants of ‘Horcoherent’ in the following characteristics:

-   -   1. Plants of the new Rose flower more continuously during the         flowering season than plants of ‘Horcoherent’.     -   2. Plants of the new Rose and ‘Horcoherent’ differ in flower         color as plants of ‘Horcoherent’ have orange, pink and         yellow-colored flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Rose plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type.

Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Rose plant.

The photograph on the first sheet comprises a side perspective view of a typical plant of ‘Chewperadventure’ ground in an outdoor nursery.

The photograph on the second sheet is a close-up view of a typical flowering plant of ‘Chewperadventure’.

DETAILED BOTANICAL DESCRIPTION

Plants of the new Rose have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype. The aforementioned photographs, following observations and measurements describe plants grown during the summer in Grand Haven, Mich., in an outdoor nursery and under commercial Rose production practices. Plants were about three years old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
